2. Do you agree with your classmate's conjecture? Given your answer for question 1 and the informationbelow, do you think the amount of water wasted by the leaky faucet over the course of 1 day is closer to theestimate of 1 cup, 1 gallon, or 1 shower? Explain your reasoning. (4 points: 1 point for circling yourestimate, 1 point forfilling in the blank, and 2 points for explaining your reasoning)
